Feature

With power and relay action indication, bright when connect and go off when disconnects.
When there is a signal in signal input, public side and common side will breakover.
It can be not used as a microcontroller development board module, but also as a home appliance control.
It can not control the or signal, but the 220V load.

Note:
1. High level flip-flops shows that there are trigger mode of the voltage between the signal input terminal and the ground; That is to say it is a way of short circuit trigger between signal input and VCC positive pole.
2. Low level flip-flops shows that there are voltage for OV trigger mode between the signal input terminal and the ground. In a word, it is a way of short circuit trigger between signal input and GND negative pole.
3. Please allow 1-3mm differs due to manual measurement.
4. Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understand
